and useful Improvements in Sprinkling or Spraying Devices, of which thefollowing is a specification.

My invention relates 'to sprinkling or spraying devices, and moreparticularly to that type used in sprinkling lawns and spraying trees band shrubbery.

One of the objects of my invention is to provide an improved sprinklingor spraying device which can be easily moved from place to place upon alawn without shuttingofi" the supply of water and without becoming wet,or which can be positioned among shrubbery without in any mannerinjuring the same. y

Another object of my invention is the provision of a device of this typein which interchangeable parts are provided to create a fog or mist, toeject a fine spray, or a drop `spray resembling rain.

Further objects are to provide a sprink ling or spraying head which canbe arranged at diiferent angles so as to direct the mist or spraydirectly upward, at an angle of 45 degrees to the vertical, or at anangle of 90 degrees to the vertical so that it niay be used in sprayingtrees, shrubbery, or

lawns by merely positioning the nozzle uponY the supply pipe or stand inaccordance with the'direction in which the mist or spray is to beejected.

A still further object is `the provision o a nozzle which will notbecome clogged in spraying insecticide fluid and by means of which thespray can be spread over a considerable area, or be directed in asubstantially straight line so as to confine the spray to acomparatively small area.

With these 'and other objects in view, my invention consists in thenovel stand or support for the sprinkling'or spraying nozzle; in thenovel features of construction of said nozzle; and in the arrangementand combination of parts to be hereinafter described and particularlypointed out in the subjoined claims.

Fig. 16 y is a cross section of a twirler memberpro- Vi 1led with non-clogging convolute channe s.

Referringnow to the drawings in detail, like numerals of reference referto like parts in the several figures.

The reference numeral 20 designates the stand or support of thesprinkler or sprayer, 30 the nozzle head and a hose 40 attached thereto.The stand or support of the device comprises a substantially circularbase 21 formed by bending a solid bar of iron into ring form andcontinuing the same inwardly, as vat 22, to the center of the base,thence upwardly, as at 23, with its extremity threaded to enter onebranch of a T-fitting 24. To another branch of said fitting the hose 40is attached, and into the third branch a tube or pipe25 is threaded,said tube or pipe being directed upwardly and having its upper endthreaded and entered into the nozzle fhead 30. The sprinkling body orsupport thus secured is adapted for sprinkling lawns, and in thisconstruction the hose is attached to said ystand or support -at a lowpoint so that by taking hold of the hose, the stand or support, may bedrawn from one place to another By thus constructing the standl thedevice in the deslred position amongrv shrubbery `and flowers. When thusused the branch of the T-itting having the hose 40 shown applied theretoin Figs. 1 and 2, is closed with a, plug 27, and the hose 4() isattached directly to the nozzle head, as at 28. In this manner the hoseis positioned above the shrubbery or flowers and will in no mannerinjure the same. The stand or support -may be easily removed and isreadily set up at any other desired point, as .may be found necessary insprinkling or spraying-shrubbery or flowers.

The nozzle head 30 is in the form of a casing having a plurality ofthreaded inletopenings 29, 31, 32, respectively, and two diverging exittubes 33, 34, the casing being provided with enlargements or bosseswhere said inlet-openings are formed. One o'f the inlet-openings isarranged in the same plane as the exit tubes 33, 34, a second at anangle of 45 degrees thereto, and the third at an `angle of 90 degreesthereto. When said nozzle is used on a stand or support, such as shownin Figs. 1 'and 2, two of said inletopenings are closed with threadedplugs 35, and when used on a stand or support, such vas shown in Fig. 3,one of said inlet-openings has the hose 40 or a fitting thereof ythreaded thereinto.

By arranging the inlet-openings as described', the nozzle be secured tothe pipe or tube 25 of the stand or support in any of three positions,in one of which the exit tubes 33, 34 are in the plane of said tube orpipe, in a second position they are arranged at an angle of 45 degreesto said tube or pipe, and in the third position they are arranged at anangle of 90 degrees tosaid tube or pipe, thus making it possible tosprinkle or spray in different directions, depending upon theheight ofthe object or objects to be sprinkled. A

By providing diverging exit tubes, an eX- i pansion chamber 36 iscreated where the exit so that the fluid will always fillv tubes join,the casing and the pressure behind the same will assure an almostconstant pressure at the escape openings of the nozzle heads, to bepresently described. The outer ends of the exit tubes are enlarged indiameter internally to provide shoulders 37, against each of which isseated a twirler member 38. Bearing against the end of each exit tubeand against Vthe marginal portion of each twirler member is a washer 39against which is seated a disk 41 having a small central escape opening42, said disk being held in position by an annulus 43 bearing againstthe marginal portion of the disk, each annulus being threaded onto anexit tube, both the space or chamber 45 of which latter are externallythreaded for this purpose. By interposing a washer between the end ofeach exit tube and the cooperating disk 41 the nozzles are made watertight and at the same time spaces or chambers 45 are. provided betweenthe twirlers and said disks.

The twirler comprises a flat substantially circular member havingcutaway portions 46 at diametrically opposite points and two convolutepassages 47, one end of each passage opening at one cutaway portion andthe other end thereof terminating and overlapping the first-mentionedend of the other groove, thus providing passages around a central raisedportion 48 which are directed gradually toward the aXis of the twirlermember. y

At points between the cutaway portions 46 each twirler is provided onthe opposite face with'spacing flanges 49. The portions 46 cut away fromthe twirler are slightly' greater than the faces of the shoulders 37'formed in the casing, which permits the fluid under pressure .to passinto the two diametrically opposite spaces 50 formed by the cutawayportions 46 of the twirler, thence into the convolute grooves 47 whereit is given /a twirling motion, thence into the space or chamber 45between the twirler and the disk 41 where it is broken up into a finespray or mist, and finally out of the escape opening 42. l

The two bodies of spray or mist ejected i from the diverging exit tubescome in contactA and become broken up outside of the nozzle body vsothat all portions within a certain area will be thoroughly sprinkled orsprayed. To a certain extentthe size of the escape opening in the disk41 controls the iineness of spray, but where a somewhat straight streamis desired, the twirler is reversed so that vthe Huid in passing throughthe diametrically opposite spaces 50 enters (shown in Fig. 7 vwithout atwirling action and consequently escapes through the escape opening in acomparatively straight line.

Where it is desired to deluge an extended surface or area with a sprayof large drops similar to rain, the twirler is provided with a number ofopenings 51 which are arranged in a circular course at the bottom of theconvolute grooves 47. This permits the water to enter the space orchamber 45 of the nozzle in larger quantities and the water entering theapertures is carried in a spiral course vwith the water entering theconvolute deluge an extended area or surface in a manner similar to rainand at times use the same for spraying, a tWirler such` as shown in Fig.15 may be used. This sprayer has the apertures 51 therein, but aclosureplate 52 is provided on the inner side of the tWirler withsimilar apertures 53 and is centrally and rotatably mounted on thetwirler so that in turning the same the apertures 5l in the twirler maybe opened or closed.

In Fig. 16 I have shown the inner Walls of the convolute grooves 47beveled, this being brought about by tapering the central portion 48 ofthe twirler. In spraying iuid insecticide, sediment and particles offoreign matter in the fluid often clog the nozzle, and by thus flaringthe inner wall of the convolute grooves the tendency of the outrushingluid is to freejthe grooves of all lodging matter, the latter beingcarried outward onto the central portion I8 of the twirler so as toleave the convolute passages free.

In Fig. l2 I have shown a cluster nozzle and in this arrangement asecond nozzle head 5l is employed, the same being connected to any oneof the unused inlet openings of the rst nozzle head by a nipple 55. Byentering this nipple in the desired inlet openings of the two nozzleheads the spray may be ejected in any desired direction, the severaljets of fluid escaping Coming in contact With each other and beingbroken up so as to assure every portion of the area sprayed or sprinkledto be thoroughly moistened. Moreover, by using a cluster, the spray orjets of water are extended over a considerably larger area.

Having thus described my invention, what I claim is,-

l. A sprinkling or spraying nozzle comprising a casing having twodiverging exit tubes and a plurality 4of inlet openings arranged at anangle to each other, a supply pipe threadedinto anyone of said inletopenings, and means for closing the remaining inlet openings.

2. A nozzle comprising a casing having diverging exit tubes, an inletopening in the plane of said exit tubes, a second inlet open- .ing at anangle ol. 45 degrees to said firstmentioned inlet opening and a thirdinlet opening at an angle of 90 degrees to said first-mentioned opening,a supply pipe threaded into one of said openings, and means for closingthe other openings.

3. A spraying nozzle comprising a casing having two diverging exit tubesand an expansion chamber common to both of said tubes, said casinghaving also a plurality of inlet openings opening into said eXpansionchamber, a supply pipe fitted to any one of said inlet openings, meansfor closing the other openings, a twirler located in each exit tube, anda disk closing the end of each eXit tube held spaced from itscooperating twirler, said disks being fastened to the exit tubes andeach having a central eXit opening.

Ll. A spraying nozzle comprising a cas ing having an exit opening and aplurality of inlet openings arranged at different angles with referenceto said exit opening, a supply pipe connected to any one of said inletopenings, and means for closing the other inlet opening or openings.

5. A spraying nozzle comprising a casing having a plurality of inletopenings, a second casing also provided with a plurality of inletopenings, and means of connection between any of the inlets of'saidcasings so as to dispose one at any of a plurality of angles Withrespect to a supply pipe and the other at any of a plurality of angleswith respect to the lfirst.

6. A sprinkling or spraying nozzle comprising a casing having aplurality of exit tubes and a plurality of inlet openings arranged todispose the casing at different angles so as to direct the sprayaccordingly, a supply pipe threaded into any one of said inlet openings,and means for closing the remaining inlet openings.

In testimony whereof I ailix my signature in presence of two Witnesses.
